[rrd-users] Still having problems

Greetings,

I wrote once before and no one responded. I'm trying to setup a RRD
database that will hold one value once a day. I'm terribly lost, the
documentation didnt make too much sense too me as far as the DB is
concerned. I tried following some examples, but I am getting really
random and unexplainable results.

I have the DB setup like this

$rrdtool create $rrd --start $timep --step 86400
DS:sql:ABSOLUTE:86400:0:10000000 RRA:MAX:0.5:1:6000

$rrdtool = path to rrdtool
$rrd = the path and name of the rrd file
$timep = some time i'm analyzing minus one day

I then input values into this DB with the following line:

$rrdtool update $rrd $time:$SQLJoinr

$rrdtool = path to rrdtool
$rrd = the path and name of the rrd file
$time = the time in seconds of the line item being analyzed
$SQLJoinr = a low integer value, typically thus far less than 20 but can
be as high as the mid thousand

I have no errors when I run through the program, and I have it
outputting the values listed above. This is where the frustrating part
comes. When I graph the values, they're not the whole integer's listed
as the value of $SQLJoinr. In fact, the numbers stored make no sense
whatsoever. I've run 'rrdtool dump' on the file to find the following:

<rrd>

Can someone please explain to me why this isnt working at all? Why does
it start all the way into the past back into the early 90's? Why does it
store the incorrect values? I know it's doing what I'm telling it to do,
and as such I know I'm making a mistake somewhere but I dont know where.
I appreciate any response regarding this.

Thanks in advance.
